Charge Carrier Injection What does this mean? A proven product - with a name for a new sensor principle which has to be taken note of. Detection principle The principle is characterized by a specially developed, gas sensitive material, which is capable of absorbing NH3 (ammonia) selectively. The adsorption of the NH3 molecules injects so-called charge carriers of ammonia into the sensor material. After many years of development, special micro-structured electrodes allow the accurate determination of ammonia concentration without the known disadvantages of semiconductor sensors or...
